Abstract:

Introduction: The aim of this study was to evaluate the prognostic value of systemic inflammatory markers, especially neutrophil-lymphocyte ratio (NLR) and platelet-lymphocyte ratio (PLR) in geriatric patients presenting to the emergency department with abdominal pain. Methods: This retrospective study was conducted in the Emergency Department of University of Health Sciences Ankara Keçiören Training and Research Hospital between 01.08.2016 and 31.12.2016. All patients over 65 years who presented with abdominal pain were included in the study. The demographic data, complete blood count parameters, diagnosis, surgical procedures, [American Society of anesthesiologists (ASA)] scores, length of hospital stay and hospital outcomes were evaluated. Results: Six hundred and eighty-eight patients were included in the study. Surgery was performed in 77 patients (12%). The most frequent diagnosis was bowel obstruction (n=57, 8.3%). There were statistically significant differences between nonsurvivors (n=91) and survivors according to 30-day mortality in terms of age, ASA score, lymphocyte count, NLR and PLR (p<0.001, p=0.03, p<0.001, p<0.001, 40 p>0.001, respectively). There were also statistically significant differences between non-survivors (n=189) and survivors according to 365-day mortality in terms of age, surgery type, lymphocyte count, NLR and PLR (p<0.001, p<0.001, p=0.009, p=0.01, p<0.001, p<0.001 respectively). In the multivariate regression analysis, the clinical feasibility of the laboratory parameters was not significant for both 30 day and 365-day mortality (p>0.05). Conclusion: According to the results of our study, we believe that NLR and PLR values do not have clinical utility as prognostic markers in determining 30-day and 365-day mortality in geriatric patients presenting with abdominal pain.
